This report is the first in a series of investigations designed to test a theory identifying the effects of conversational trade-offs between selected maxims on public attitudes toward augmentative and alternative communication (AAC) system users and their communication. In the current study, the trade-offs between the relevance of a prestored message and its speed of delivery were examined. Participating were 96 sales clerks. Twelve scripted videotaped conversational conditions, involving an AAC customer and a clerk at a checkout counter, were used to manipulate message relevance, speed of message delivery, and participant/AAC user gender. Following each assigned viewing, participants completed a questionnaire designed to assess their attitudes toward the AAC user and his or her communication. Significantly higher mean ratings were found for the conditions involving the slowly delivered relevant messages (both preceded by a conversational floorholder and without a floorholder) when compared to the quickly delivered partly relevant message condition. In addition, the condition involving the slowly delivered relevant message with a floorholder yielded significantly higher mean ratings than that without the floorholder. There was no effect for participant/user gender. Modifications of the theory and technological implications are discussed.
本报告是一系列调查中的第一篇，这些调查旨在检验一种理论，该理论确定了特定准则之间的对话权衡对公众对辅助和替代沟通（AAC）系统用户及其沟通方式的态度的影响。在当前的研究中，研究了预先存储的信息的相关性与其传递速度之间的权衡。参与研究的有96名售货员。使用了12种脚本化的录像对话情境，其中涉及一名AAC用户和一名在收银台的店员，以操纵信息相关性、信息传递速度以及参与者/AAC用户的性别。在每次指定观看后，参与者完成一份问卷，旨在评估他们对AAC用户及其沟通方式的态度。与快速传递的部分相关信息情境相比，涉及缓慢传递的相关信息的情境（无论是在对话引导语之前还是没有引导语的情况下）的平均评分显著更高。此外，涉及有引导语的缓慢传递的相关信息的情境产生的平均评分显著高于没有引导语的情境。参与者/用户的性别没有影响。讨论了该理论的修改和技术含义。
